三峡水库区间流域实时水文预报系统研究

The research of hydrology forecasting proposal program on real time runoff and flood in the Three Gorges Reservoir area

介绍了应用新安江模型和API型模型编制三峡区间实时水文预报系统的方法.由三峡水库蓄水前、后资料对预报模型的检验表明,新安江模型预报精度满足实时洪水预报的要求.本系统已安装在三峡开发总公司梯级调度中心正式运行.

Based on optimizing the runoff generation and flow concentration parameters of representative watershed in the Three Gorges intervening area, adopting Xinanjiang model and API model respectively to work out hydrology forecast program, and examining the data of the Three Gorges Reservoir before and after it stored water, the research shows that the forecast program authorized by Xinanjiang model has better effect in flood and runoff forecast and meets with the standards which are formally issued by Hydrological Information and Hydrological Forecasting. Now, the forecast program has been adopted in the cascade dispatch center of Three Gorges Development Corporation.
